Glaucoma: Causes, Symptoms and Treatment

Glaucoma is a set of eye diseases that cause damage to the optic nerve and leads to a loss of vision. It is characterized by high intraocular pressure (IOP). Some types of glaucoma are open-angle glaucoma, normal-tension glaucoma and closed-angle glaucoma. It is caused by a variety of factors such as diet, genetics, ethnicity, etc. If untreated, it can result in blindness, which cannot be reversed. Its symptoms include blurred vision, redness of the eye, mid-dilated pupil, severe eye pain and nausea. The screening for glaucoma is performed by a standard eye examination or by techniques like tonometry, gonioscopy, scanning laser ophthalmoscopy, optical coherence tomography, etc. The mainstay of glaucoma treatment is lowering IOP through various pharmaceutical and surgical interventions. The objective of this book is to give a general view of the different causes, symptoms and treatment methodologies of glaucoma. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included in this book. It will serve as a valuable source of reference for graduate and postgraduate students.
